Install Ventilation Duct<\/h2>\n\n\n\n

Install Ventilation Duct Ventilation duct mainly refers to the ventilation duct of central air conditioning system, which we often ignore it, but it is an important part of air conditioning system. It is a kind of metal or composite pipe for ventilation and air conditioning engineering of industrial and civil buildings. It is a municipal infrastructure to make the air circulate and reduce the concentration of harmful gases.<\/p>\n\n\n\n

  1. For more complex civil buildings, in the design stage, each type of work (HVAC, water supply and drainage, power supply and lighting, and Architecture) should first negotiate the space separation, and determine the elevation range of each kind of pipe. In general, they should not go beyond the limits set for themselves. In case of the crossing of individual pipe sections, it is necessary to negotiate with other projects.

  2. The principle to solve the collision and coordination of various ventilation pipes is generally: “small pipes give way to large pipes, and pressure gives way to no pressure”. For example, if the water pipe collides with the air pipe, the water pipe should be turned. If the cold and hot water pipes collide with the downpipe, the cold and hot water pipes should be changed.

  3. Before construction, the Engineer in charge of the main equipment shall draw the pipelines and single lines of each type of work on a plan. One-color pen for each type of pipe. Integrate the elevation of each intersection to see if there is any contradiction, find it in time, and solve the problem before installation. Install Ventilation Duct<\/li>\n\n\n\n
  4. In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as water pipes, fire spray pipes, etc.). Install Ventilation Duct<\/li>\n<\/ol>\n\n\n\n
